Abstract
It the utility model is related to a kind of solid polymer electrolyte membrane water electrolyzer, including side plate, felt pad, flow deflector, anode flow field, membrane electrode and cathode flow field, membrane electrode is by quaternized 2,6 dimethyl polyphenylene oxide are formed as electrolyte, sealing gasket is provided between each several part, composition water electrolyser unit is sequentially connected according to structural order, two or more water electrolyser units are locked by metal bolts tie spacer, nut, form water electrolyser group.The present apparatus has the conductivity for compared with high ion exchange volume, preferable mechanical performance and chemical stability, improving electrode intermediate ion, and cost is also far below the conventional solid polymer water electrolysis unit being made up of acid solid polymer dielectric.
Description
Technical field
A kind of pure water electrolysis unit is the utility model is related to, more particularly to a kind of alkali solid polymer electrolytic ionic membrane
Pure water electrolysis unit.
Background technology
Hydrogen energy source has extensive development prospect as clean energy resource.The method of pure water Electrowinning hydrogen is because with carbon-free
Discharge, efficiency high, it is pollution-free the features such as and receive much concern.The core of pure water electrolysis unit is by polymer dielectric and Catalytic Layer
The membrane electrode of composition, specifically by either physically or chemically adding anode and cathode Catalytic Layer in the both sides of ionic membrane.Solid gathers
The core of polymer electrolyte technology for hydrolyzing is the chemical reaction occurred on membrane electrode and membrane electrode.
A kind of existing solid polymer pure water electrolysis unit usually used similar Nafion (sulfonic group perfluorinated cations
Exchange membrane) acid solid polymer as electrolyte, and need the rare precious metals such as platinum simultaneously as catalyst.This kind of device
Possessed high cost, it is unstable in alkaline environment the problems such as its commercialization is affected.Research and develop and use combination property
Preferably electrolyte ion film, raising electrode catalyst activity, the preparation of improvement membrane electrode, raising equipment pressure management etc. can be excellent
Change solid polymer electrolytic water installations.
Utility model content
Technical problem to be solved in the utility model is that water electrolyser cost is too high in the prior art, and in alkaline ring
The problems such as unstable in border.
The utility model is as follows to solve the technical scheme that above-mentioned technical problem is taken：
A kind of solid polymer electrolyte membrane water electrolyzer, it is characterised in that：Including side plate, felt pad, flow deflector, anode
Flow field, membrane electrode, cathode flow field, the dimethyl polyphenylene oxide of membrane electrode quaternized 2,6 are formed as electrolyte, are set between each several part
There is sealing gasket, form water electrolyser unit successively according to structural order, by metal bolts tie spacer, nut by multigroup water electrolysis
Groove is locked, and forms water electrolyser group.
The substantive distinguishing features and progress that the utility model has are：
1. quaternized 2,6 dimethyl polyphenylene oxide are the good conductors of ion, by OH- anionic electroconductives, therefore by quaternized
The anion-exchange membrane that 2,6 dimethyl polyphenylene oxide are formed has steady compared with high ion exchange volume, preferable mechanical performance and chemistry
It is qualitative, continuous ion-conducting networks can be formed in Catalytic Layer, improve the conductivity of electrode intermediate ion.
2. because the alkaline environment of alkaline solid polymer electrolyte water electrolyzer allows membrane electrode your non-gold used
Catalyst as efficient stable of category and its oxide, its cost are consolidated well below must use the acidity of the precious metal catalysts such as platinum
The conventional solid polymer water electrolysis unit of body polymer dielectric composition.
